LUBRICATING DEVICE.

Application ,led May 19, 1924. -Seria1 No. 714,211.

This invention relates to the supplying of lubricating oil to automobileengines.

The objects of the invention are to make it possible for a motorist t0carry a supply of lubricating oil in a clean, handy transportable formand to suppl the oil to the motor as required without soi ing the handsor the The foregoing and other objects are attained in this inventionthrough certain novel features of construction, combinations andrelations of parts as set forth in the following specification. y

In the drawings accompanying and yforming part of this specification,simple and practical embodiments of the invention are illustrated but itshould be understood that the structural features may be modified andchanged in various ways without departure from the spirit and scope ofthe invention as hereinafter defined and broadly claimed.

Figure l is a broken and part sectional side elevation of the combinedholder and opener as applied to the oil intake of an engine and showingone of the sealed oil containers of the invention as being inserted inthe holder,

. Figure 2 is abroken sectional view illustrating the general relationof the holder to the crank case of the motor, showing the can ascompletel seated in the holder and punctured to ena le the oil to flowinto the crank case. Figure 3 is a horizontal sectional view of theholder on substantially the plane of line 3- 3 of Fig. 1.

the can, a lighter cover construction .and a shut-oli valve hetweenthecasing and .the oil intake.L Figure 6 is a detached side elevation ofthe one piece spring support. Figure 7 is a horizontal sectionalview ofthe casing. The illustration of a motor. in Fi 2 1s typical as showinghou7 they are usual y provided with an oil intake 5 in the side or topof the crank case, this intake being ordinarily 'in the form of a shortstandpipe equipped with a screw cap or other suitable closure.

A feature of the invention is the utilization of this oil intake as asupport fora special holder ldesigned to receive a sealed container ofoil and provided with means for automatically opening the sealedcontainer by the simple act of placing the same within the holder.

In a preferred form, the sealed containers are made of substantiallysquare or rectangular shape to facilitate handling and save space instorage. One of these substantially square containers is illustrated at6 and the holder for the same shown at 7 is of c0rrespondinglyrectangular or square outline to receive and hold the container with afairly snug fit.

To meet a condition like that illustrated, where theoil intake isequipped with a screw cap, the oil can holder is simply formed with ascrew socket 8 in its lower end and is supported on the intake by simplybeing screwed onto the upper end of the same in place of the originalscrew closure.

The automatic opening of the sealed can is accomplished in theillustration by mounting a cutter 9 on the bottom of the holder and byproviding the holder with a hinged cover 10 carrying a cutter 11 forpuncturing the top of the can. interchangeable, each consisting of apointed triangular blade grooved orfluted at 12 on the rearward face ofthe same to provide free flow for the oil or air and having a screw stem13 by which the same may be secured' with nuts 14 to the bottom or tothe cover of the holder.

The cover of the tank or holder is secured closed by suitable means suchas the hinged link shownv at 15 adapted to snap over the keeper lug 16on the front wall of the holder.

A spring follower is shownprovided at 17 in the bottom of the holder foryieldingly supporting the can and holding the same against rattling.This spring follower is shown in the form of a ring engaged by a coilspring 18 supported in an enlargement 19 forming a spring seat in thebottom of .the holder and the same in addition to the functions`mentioned, operates to partially eject the emptied can when thev coveris opened.

The sealed oil packages, lacking screw These cutters'are shown asclosures or other outlets, aresimple to make and canbe produced quiteinexpensively `and n a number of' them can be packed together withoutanywaste space. This makes it'possible and convenient for a motorist tocarry one or al number of the packages as a reserve supply, which can befed to the 7motor when required, yby simply slipping the cans into theholder and closing the cover down over the same. In puncturing thebottom kof the can, the metal is'bent back somewhat around the openingand this provides a slight cavity to collect any sediment that may bepresent.` The mounting of the holder onthe oil intakecauses the same tobe supported within the region of the motor cylinders and i, usuallyfairly close to the radiator so that the oil will be warmed suicientlyto cause it to yflow freely down into the crank case. The opening i ofthe f cover venables the spring follower to lift theeinptied can farstance, vwhenthe crank case is'to be washed yout with a. flushing oil,yf yIn the'modified construction illustrated inr Figures 5 to 7 thevlower cutter is shownr formed as a sharp pointed triangular spur madeintegral with the ybottom of the case and the upper cutter is shown asasharp pointed spur Qlriveted or suitably secured to the under side ofthe cover 22, which in this instance is shown made of sheet metal hingedon the back of the case at 23 and secured in closed relation by anintegral spring catch 24.

The spring follower also is of simplified construction in that it ismade of a single piece of spring metal having a raised centra]supporting portion 25 and bowed spring arms Q6 which rest on the bottom27 of the casing at the sides of the discharge outlet.

The integrally formed can opening spur is shown as raised above thefloor of the bottom on a pedestal or table projection 28 provided in onecorner of the case which may act as a stop for the end of the can toprevent the can being pressed down so far as to flatten the bowed springsupport and close otf the discharge outlet and this pedestal also mayassist in positioning the spring support by preventing the same fromtwisting around in the bottom of the case.

If desired, a shut-off valve 29 may be interposed in the oil intake.This valve enables the flow of oil into the crank case to be governed atwill and is useful, for instance, in a case where it is desired to warmthe oil before permitting it to flow into the crank case. This controlalso enables only a portion of the can being used at a time andrallowsfor a quantity ofoil inbulk being carried `in the casingandl'lowedinto the crank case whenever it may be desired.

What is claimed is: 1. Anoil canholderadapted to be connected tothe oilintake of a motor, comprisinga tank of non-circular cross-section'havinga bottom, a cut-ter'mounted above said bottom, a hinged cover ofnon-circular crosssection :forsaid tank provided with a cutterpositioned between the center and the hinge side of said cover, saidcutter being adapted to puncture a Tpermanently sealed container of across-section corresponding to that of said tank vand inserted insaidholder wheny said cover is closed, and a spring follower in said tankfor lifting said container when said cover is opened to permit graspingsaid container by. the fingers to'remove it'frorri said tank.
